This is beyond creepy if you value your privacy, and who doesn't. One of the world's No. 1 cellphone makers is using sounds that humans cannot hear to spy on you.

They are called beacons. They are so invasive that Google recently banned all apps using beacons.

They use ultrasonic sound to track what you're doing, whether you're shopping, at a restaurant eating, visiting websites and more. The sounds are hidden in websites, apps, in-store devices, television ads and other devices.

When the sound is emitted, it alerts your smartphone to start keeping track of you. In some cases, it uses your microphone to record you.

The worst part about Samsung's spying is that the company has cleverly tricked you into agreeing to it. It discloses in its Privacy Policy that it uses beacons - however, you must read the fine print.

Here's what it says, in part:

"We, along with certain third parties, also may use technologies called beacons (or “pixels”) that communicate information from your Product to a server. Beacons can be embedded in online content, videos, and emails, and can allow a server to read certain types of information from your Product, know when you have viewed particular content or a particular email message, determine the time and date on which you viewed the beacon, and the IP address of your Product. We and certain third parties use beacons for a variety of purposes, including to analyze the use of our Services and (in conjunction with cookies) to provide content and ads that are more relevant to you."

Of course, if you're like most people, you just scroll through endless pages of privacy policies and agree to the company's terms. So, what can you do?

You can contact Samsung and tell them you do not want them tracking you with beacons. Better yet, contact your U.S. representative and let them know about your concerns. Find your representative here.
